Like BSA, La Fabrique Nationale d'Armes de Guerre ('FN', for short) began as a munitions manufacturer, turning to the production of motorcycles in 1900. Today the Belgian company is best remembered for its sensational four-cylinder models, the first of which appeared in 1904 and was first exhibited publicly at the 1905 Paris Cycle Show. Designed by Paul Kelecom, the FN was the world's first practical four-cylinder motorcycle, its smooth and almost vibration-less operation setting it apart from rival singles and v-twins. Advanced for its day, the 362cc air-cooled four featured 'atmospheric' inlet and mechanical (side) exhaust valves and a robust five-bearing crankshaft. Shaft final drive was another innovation. At first there was no clutch, the direct-drive machine being started by pedalling away until the engine fired. Two brakes (drum and rim-type) operated on the rear wheel. The engine was enlarged (to 413cc) in 1906 and again around 1908, on this occasion to 498cc, while in 1911 the factory introduced its own two-speed transmission, similar to that already offered by Horstmann in Britain, which was contained within the drive-shaft housing. This partly restored FN Four was purchased by the current owner in Argentina in 2009 (EU taxes have been paid). Parts restored include the wheels and brightwork but there are some components missing and the machine does not run. Sold strictly as viewed, it comes with current Belgian and old Argentinian registration papers.

  • FN 498c cm3 quatre cylindres c.1913
    Cadre n° 50361
    Moteur n° 1140

    Comme BSA, la Fabrique Nationale d'Armes de Guerre (en abrégé FN) commença par produire des munitions et aborda la production de motocycles en 1900. De nos jours, la firme belge est très connue pour ses magnifiques modèles à moteurs quatre cylindres dont le premier apparut en 1904 fut exposé pour la première fois en public au salon du cycle de Paris de 1905. Conçue par Paul Kelecom, la FN fut la première moto quatre cylindres viable du monde, sa douceur de fonctionnement et son absence presque totale de vibrations la démarquant nettement de ses concurrentes monocylindres et V-twin. Moderne en son temps, le quatre-cylindres de 362 cm3 refroidi par air était muni de soupapes d'admission atmosphériques et d'échappement (latérales) commandées et d'un robuste vilebrequin à cinq paliers. La transmission secondaire par arbre était aussi une innovation. Initialement, la machine n'avait pas d'embrayage, le démarrage s'effectuant par pédalage jusqu'au lancement du moteur. Deux freins (à tambour et sur la jante) s'appliquaient sur la roue arrière. Le moteur fut agrandi à 413 cm3 en 1906 puis de nouveau en 1908, cette fois à 498 cm3, tandis qu'en 1911, l'usine introduisait sa propre boîte à deux rapports semblable à celle que proposait Horstmann en Grande-Bretagne et qui était intégrée au carter de l'arbre de transmission.
    Cette FN quatre cylindre partiellement restaurée fut achetée par le propriétaire actuel en Argentine en 2009. (Droits et taxes acquittés au Royaume-Uni). Les parties restaurées sont les roues et les pièces plaquées, mais certaines pièces sont manquantes et la machine ne fonctionne pas. Vendue strictement en l'état, elle est accompagnée de ses papiers d'immatriculation argentins précédents et belges actuels.
